AWS SolidStart WebSocket endpoint

Tip

This page is best viewed through the site search or through the AI.

Deploys a SolidStart app with a WebSocket endpoint in a container to AWS.

Uses the experimental WebSocket support in Nitro.

app.config.ts

export default defineConfig({
  server: {
    experimental: {
      websocket: true,
    },
  },
}).addRouter({
  name: "ws",
  type: "http",
  handler: "./src/ws.ts",
  target: "server",
  base: "/ws",
});

Once deployed you can test the /ws endpoint and it’ll send a message back after a 3s delay.

sst.config.ts

const vpc = new sst.aws.Vpc("MyVpc", { bastion: true });
const cluster = new sst.aws.Cluster("MyCluster", { vpc });

new sst.aws.Service("MyService", {
  cluster,
  loadBalancer: {
    ports: [{ listen: "80/http", forward: "3000/http" }],
  },
  dev: {
    command: "npm run dev",
  },
});
